    I'm currently using Qt Creator 4.11.0
    Python: 3.8
    PySide 2 version 5.14

    When I'm trying to import QAbstractSeries from QtCharts I am getting an import error.

    # This Python file uses the following encoding: utf-8
    import sys
    
    from PySide2.QtWidgets import QApplication
    from PySide2.QtQml import QQmlApplicationEngine
    from PySide2.QtCore import QObject, qDebug, Signal, Slot, Property
    from PySide2.QtCharts import QAbstractSeries
    
    from audio.__main__ import test
    
    class Main(QObject):
    
        axisChanged = Signal()
    
        def __init__(self):
            QObject.__init__(self)
            self.axisY = 0
    
        testSignal = Signal(QAbstractSeries, arguments=['setYpoints'])
    
        @Property(int, notify=axisChanged)
        def setAxisY(self):
            self.axisY = 150
            return self.axisY
    
        def runOther():
            audioChunk = test()
            print(audioChunk)
    
        @Slot(QAbstractSeries)
        def setYpoints(self, series):
            print(series)
    #        audioChunk = test()
    #        for x in range(len(audioChunk)):
    #            yPoint = audioChunk[x]
    #            self.testSignal.emit(yPoint)
    
    if __name__ == "__main__":
        app = QApplication(sys.argv)
    
        dataToUI = Main()
    
        engine = QQmlApplicationEngine()
        engine.rootContext().setContextProperty("dataToUI", dataToUI)
        engine.load('ApplicationWindow.qml')
        engine.quit.connect(app.quit)
    
        Main.runOther()
    
        sys.exit(app.exec_())
    
    

    Output:

    ImportError: cannot import name 'QAbstractSeries' from 'PySide2.QtCharts' (D:\4. Projecten\WLED_Entertainment\wled\lib\site-packages\PySide2\QtCharts.pyd)

    The path leads to a virtual env that I have created.

    Any help is appreciated, thanks!

      Hi and welcome to devnet,

      Can you import the module itself ?

        Yes I can when I import the module I can compile without any errors.

        When I do:

        import PySide2.QtCharts
        
        #And within the code I use:
        
        QtCharts.QAbstractSeries
        

        Output:

        NameError: name 'QtCharts' is not defined

          If you want to use it like that, you have to write:

          from PySide2 import QtCharts
